appears when drilling holes or during renovation. Please note that improper maintenance can lead to damages which are not covered by

them in any way.
Don’t touch the power cord with wet hands. If the power plug has gone wet or dirty, dry or clean it with a dry cloth thoroughly. Never
ever immerse the power plug or the whole unit into water.
If the unit falls into your aquarium first shut off the power supply (fuse or circuit breaker) then pull the power plug from the wall outlet.

Intended use
Technical data
The dosing unit should only be used to dose with following liquids in aquarium or pond:
▪(Salt) water
▪Standard supplements for aquariums and ponds like fertilizer and trace elements (suited for
iodine)
▪Balling salts
Location
Dosing pumps are self-priming and should be placed above the liquid container. This prevents the drainage of the container in
case of leakage. The tube on the intake side of the pump should be kept short. To avoid a backow, the tube must not hang in
the aquarium water. Make sure that hose connections can not detach themself, plug the hoses as far as possible on the pump
fitting, use only suitable hoses and avoid the tensile strain.
Pump heads can be rotated 180°. Therefor press both latches and pull the pump head off, rotate and push it carefully onto
the motor shaft. Make sure that the motor shaft goes between pressure rollers — do not use force. The pump head latches
should snap in the front panel.
